Decisiononly workflow webservice - asmx page blank
I hope I'm missing something simple but I'm trying to setup a decision-only project as a webservice to be called from other workflows/systems, I've created a new decision-only project and setup a series of invocation target workflows within and set the input/outputs as needed, I have then published the workflow and accessed by the standard asmx page, but this is totally blank, no errors in the symantec log or IIS log, I've compared my settings to the SD.DataServices & the AM.Dataservices projects and settings are a exact match including the web.config files but the main page is still not showing the list of methods i should be able to call. I've restarted the Server extensions and done a IISReset, I tried to generate a integration library web caller but got a error (see below)
Cannot get request from URL:
System.InvalidOperationException: There is an error in XML document (0, 0). ---> System.Xml.XmlException: Root element is missing.
at System.Xml.XmlTextReaderImpl.Throw(Exception e)
at System.Xml.Serialization.XmlSerializer.Deserialize(XmlReader xmlReader, String encodingStyle, XmlDeserializationEvents events)
I've attached screenshots of my settings.
Using Workflow 7.1.1500.2062
